don't call your evil ex...

... or risk interrogation from friends, or worse, embarrassment on Facebook with this mobile app from Brazilian soft drink, Guarana Antarctica.

It's pretty simple: friends of the heartbroken set up the app to prevent the victim of heartbreak from breaking down and calling their ex. If they have a weak moment, it blocks them from calling, alerts their friends, and if all else fails, auto-posts to Facebook to mock them publicly for being weak.
